(b) Looking at the horizontal forces at that point leads to 21 sin35 (49N)sin35 28N. TT = ° = (c) We denote the components of T 3 as T x (rightward) and T y (upward). Analyzing horizontal forces where string 2 and string 3 meet, we find T x = T 2 = 28 N. From the vertical forces there, we conclude T y = w B =50 N. Therefore,
